The corresponding determining neutral matrix equations are established, and an explicit solution is derived through the construction of a neutral discrete delayed matrix exponential based on these equations. A couple of examples with simulations are provided to verify the theoretical findings and to illustrate the efficiency and applicability of the developed results.eninfo:eu-repo/semantics/closedAccessNeutral Difference Delayed SystemFractional DifferenceDetermining Neutral Matrix EquationNeutral Discrete Delayed Matrix ExponentialArticle
